Create At   : 2025/04
Owner       : haomeng
Description :
    1、查看集群状态
    2、运行tpcc业务
    3、修改主节点stat文件权限为不可用
    4、查看业务运行情况
    5、重启集群
    6、恢复state文件权限
    7、拉起被踢出节点
    8、恢复集群初始状态，查看集群状态
Expect      :
    1、集群状态正常
    2、运行业务成功
    3、修改主节点stat文件权限成功
    4、业务运行正常无影响
    5、重启集群失败，原主节点被踢出
    6、恢复state文件权限成功
    7、拉起被踢出节点成功
    8、恢复初始状态成功，集群状态正常
